Nine Boynton Beach place-name ZIPs, one county
Boynton Beach sits in Palm Beach County on Florida's Atlantic coast, between Lake Worth Beach to the north and Delray Beach to the south. DialWick's county column comes from GeoNames' US postal-code export (CC BY 4.0), retrieved 2026-08-03, not from a live scrape of USPS's web lookup form.
Commercial directories such as zip-codes.com describe the same nine codes as six standard ZIPs plus three PO Boxes and place them in Palm Beach County, which matches this extract [zip-codes.com: Boynton Beach, FL, data last updated note on that page read 2026-10-19].
Palm Beach County's own planning maps label the municipal area among the coastal ZIP polygons that include 33426, 33435, 33436, 33437, 33472, and 33473; they do not invent a second county for the city name [Palm Beach County PZB ZIP map PDF, printed legend dated Dec 02 2021, checked 2026-10-19].

Standard delivery vs PO Box ZIPs
If you are filling a shipping or voter form, the six standard codes are the ones tied to street delivery. 33424, 33425, and 33474 exist for post-office box ranges; they still carry the Boynton Beach place name in GeoNames, but they are not residential street ZIPs.
Alias place names show up on some commercial pages for 33435 (Ocean Ridge, Briny Breezes) and 33436 (Village of Golf). Those aliases describe acceptable or related place strings for the same five-digit code; they do not move the ZIP into another county in this dataset.
There is no single "main" Boynton Beach ZIP. Coastal and central neighborhoods commonly use 33435 or 33426; western tracts more often use 33437, 33472, or 33473. The only reliable way to pick one is the address's own five digits.
How this differs from multi-county city pages
Some Florida and Georgia cities in this series need a county-split warning because GeoNames (or competing directories) put different ZIPs under different counties for the same city string. Boynton Beach is not one of those cases in the current extract: all nine rows say Palm Beach.
That does not mean municipal limits and ZIP polygons are identical. ZIP boundaries follow carrier routes; city limits follow annexation history. Mail can show Boynton Beach while the parcel sits near a neighboring municipality's edge.
